[0051] A sampling method for an original arsenic sandstone sample portable sampling device comprises the following steps:

[0052] S1: Determine the size of the sample to be taken. At the selected sampling location, use 1-2 times the designed sampling side length as the boundary and manually excavate to the designed sampling depth.

[0053] S2: Observe and judge whether the excavation depth is within the set lithology. If not, reselect the sampling position. If yes, go to step S3.

[0054] S3: Expand the working surface around the proposed sampling location to facilitate the operation and transportation of samples by operators.

[0055] S4: Draw a line on the layer to be sampled at a length of 1.2 times the side length of the intended sample, and use a high-pressure steam gun to scrape the arsenic sandstone sample along the drawn line into a rock block the size of the inner diameter of the sampling device.

[0056] S5: Put the pre-prepared sampling device aside, open the four side panels of the sampling device, and lay plastic film on the inside of the sampling device.

[0057] S6: Use a high-pressure steam gun to cut off the bottom end of the rock block, lift the rock block from its original position, use tools such as a soil chipper and an alloy hacksaw to scrape the surface of the rock block, and discard the steam-soaked part.

[0058] S7: Place the rock block in the sampling device, close the side panels, and fill the gaps in the sampling box with fine sandstone particles near the sampling point.

[0059] S8: Use a soil scraper to scrape the upper part of the sample inside the sampling device flat, close the plastic film, and ensure that the plastic film completely seals the sample.

[0060] S9: Cover the top cover of the sampling device and fasten all the buckles on the sampling device.

[0061] S10: Wrap the sampling box with 100-mesh gauze, and then fix it with wire. Use a brush to evenly apply the hot-melt liquid paraffin on the emery cloth and let it stand until the paraffin condenses.

[0062] S11: Number the processed samples, wrap them in plastic film, secure them with tape, and transport them to the laboratory.

[0063] The sealing working principle of the portable sampling device for original arsenic sandstone samples in this utility model is as follows:

[0064] (1) Before loading the sample, spread the sampling device flat, and then spread a 230×230 cm plastic film flat. This measure is intended to reduce the water loss of the sample and to ensure the original physical properties of the sample as much as possible.

[0065] (2) When closing the side plate of the sampling device, fill the pores between the block sample and the plastic film with fine sandstone particles (the fine particles should be taken from near the sampling point), and try to make the plastic film fit the sample without leaving any gaps.

[0066] (3) When the plastic film is closed over the sample, try to ensure that the plastic film is flat and every part of the sample is covered by the plastic film, and then fix it with tape.

[0067] (4) After closing the top cover and fastening all the buckles, wrap a layer of dense gauze around the outside of the box, secure it with wire, and evenly apply hot-melt liquid paraffin to the dense gauze. This measure is intended to provide sufficient sealing using the condensation-formed sample protection material to maximize the protection of the physical properties of the sample.

[0068] (5) Wrap a layer of plastic film around the gauze coated with paraffin wax and secure it with tape. Because paraffin wax is brittle and will inevitably get bumped during transportation, the main purpose of the second layer of plastic film is to prevent the paraffin wax from falling off and to act as a reseal.

[0069] (6) The dense mesh gauze used in the sealing process is required to be above 100 mesh, and the plastic film is made of low-density polyethylene film (LDPE).

[0070] Working principle of high pressure steam adjustable elbow gun:

[0071] (1) Because arsenic sandstone is easily dispersed when exposed to water, a high-pressure steam gun is used to cut arsenic sandstone blocks to achieve the purpose of efficient sampling.

[0072] (2) The gun head of the high-pressure steam adjustable elbow gun is a 0°-180° rotating gun head, which can be adjusted to the appropriate position at will to meet various field conditions.

[0073] (3) The high-pressure steam gun barrel is a telescopic barrel (length is 10cm-100cm), which can be adjusted to a suitable position to meet various field conditions.

[0074] (4) The water pump used for the high-pressure steam gun is a high-pressure water pump with a water pressure range of 0MPa-100MPa.

[0075] (5) The high-pressure steam gun is powered by a lithium battery with a battery capacity of 20,000 mAh.

[0076] (6) The water required for the high-pressure steam gun is drawn from a portable water bucket, the length of which is 5m-20m.

[0077] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that they can still modify or replace the technical solution of the present invention with equivalents, and these modifications or equivalent replacements cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of the present invention.
